THE CHESS RULES
Remember that your computer knows the rules of the game, including the
rules about castling, en passant captures, pawn promotion and stalemate. It
will never break any of these rules. Sometimes it may seem that the computer
has made an irregular move. What may have happened is that you
accidentally made a mistake when entering a move, or you may have
accidentally put one or more of the chess pieces on the wrong square during
the game. If this happens, you should verify the locations of all the pieces by
using “Verify Position” mode.
If you are in any doubt about the rules of chess, you should take another look
at the U. S Chess Federation’s “Let’s Play Chess” rules found in your box.
En Passant
For an “En Passant” capture, press the FROM and TO squares of the
capturing pawn. The square of the pawn being captured will then appear on
the display. This is to remind you to remove the captured pawn. You must
press down on the captured pawn before removing it from the board.
C a s t l i n g
The computer automatically recognizes castling maneuvers after the King is
moved two squares. After you have pressed the King down on its FROM and
TO squares, IVAN’S display will remind you to press down on the Rook’s
FROM and TO squares to finish the move. Remember you must always
move the King first when castling. It is illegal to move the rook first. See U.
S. Chess Federation’ s rules of chess if you do not fully understand the rules
for Castling.
Pawn Promotion
For Pawn Promotion, make your next pawn move to the last row as usual.
Then, press the piece symbol button for the desired piece to enter your
promotion choice into the computer. The computer immediately recognizes
your new piece, and begins thinking about its next move. The computer can
also under promote. Under promoting is when you would like another piece
other than the Queen. If you wanted, let’s say, a Knight you would just press
the Knight symbol when promoting your pawn. When the computer
promotes, it displays the newly promoted piece. Remember to change the
piece on the board after a pawn promotion.

TOO EASY OR TOO HARD? CHANGE THE LEVEL
When the computer is first turned on, it is set to Level 6, which is the weakest
level. However, you may choose a different level. To change the level, simply
press LEVEL and the computer will display the current playing level. You can
change levels one at a time by pressing the arrow buttons or by 10 levels at a
time by holding down the arrow button for a full second. To lower the level of
play press the arrow pointing to the left. To raise the level press the arrow
pointing to the right. Continue pressing the desired arrow until the level you
want appears in the display. When you have selected your desired level, press
the CLEAR button and continue playing.
PIECE SYMBOLS SHOWN IN THE DISPLAY
CAPTURING MOVES
Captures are performed just like any other move. The moving piece is pressed
down on the FROM and TO squares while the captured piece is removed
from the board without being pressed. If the computer makes a capture move
it flashes the right most : Symbol when displaying the FROM and TO
squares on the LCD.
When making an en passant capture, the computer directs you to move the
capturing pawn in the usual way. It then indicates the square from which the
captured pawn is to be removed. Press down with this pawn as you remove it
from the board.
